Switch zoning for Hitachi HUS 100 family storage systems
Switch zoning configurations for the Hitachi HUS 100 family system include fabric zoning, target port sharing, host splitting, and controller splitting.
The Hitachi HUS 100 family system has no zoning limitations.
The Hitachi HUS 100 family systems present themselves by default to the Storwize® V3500 system as separate controllers for each port that is zoned to the Storwize V3500 system. For example, if one of these storage systems has four ports that are zoned to the Storwize V3500 system, each port appears as a separate controller rather than one controller with four WWPNs. A given logical unit (LU) must be mapped to the Storwize V3500 system through all controller ports that are zoned to the Storwize V3500 system by using the same logical unit number (LUN).
Fabric zoning
When you zone a Hitachi HUS 100 family storage system to the Storwize V3500 backend ports, be sure to have multiple zones or multiple Hitachi HUS 100 family storage system and Storwize V3500 ports per zone to enable multipathing.
Target port sharing
The Hitachi HUS 100 family storage system can support LUN masking to enable multiple servers to access separate LUNs through a common controller port. In this setup, there are no issues with mixing workloads or server types.
Host splitting
To prevent multipathing driver incompatibility issues, avoid connecting a host to both the Storwize V3500 system and a Hitachi HUS 100 family system at the same time.
